Description

[0001]
BACKGROUND OF THE INVENTION This invention relates generally to drawer slides, and more particularly to bearing retainer holding devices for drawer slides.
[0002]
Nested slides for drawers and others are often desired for applications where cabinets or other shelves are mounted. Such a sliding body allows easy access to the inside of the drawer. These slides hold the drawer in a horizontal position regardless of how far the drawer is withdrawn from the cabinet. A typical drawer slide has two or three sliding members that are slidably connected by a set of bearings that ride on a track formed thereon, i.e., rolling. ing. Individual bearings within a set of bearings are often held relative to each other by bearing retainers.
[0003]
One type of drawer slide is a telescopic drawer slide. In a telescopic drawer slide body, various slide members constituting the drawer slide body are stacked in a telescopic manner and extend so as to be stretchable. For illustration purposes, the outer sliding member is connected to a cabinet or enclosure, but it will be appreciated that the inner sliding member may be connected to a cabinet or the like instead. When the outer sliding member is connected to the cabinet or enclosure, the sliding member attached to the drawer is the inner sliding member. The three-element telescoping slide additionally includes an intermediate sliding member connected between the outer sliding member and the inner sliding member in normal times.
[0004]
Each drawer sliding member of the outer sliding member, the inner sliding member, or the intermediate sliding member generally comprises a vertical web having bearing tracks extending horizontally from the upper and lower edges. Furthermore, for the two-element drawer slide, the bearings that slidably connect the outer and inner slide members are often held by a common bearing retainer. For a three-element drawer slide, the innermost set of bearings in the vertical direction and the bearing that slidably connects the inner and intermediate sliding members are often held by a common bearing holder. . These common bearing holders generally have a shape in which the drawer sliding member is mirrored. Thus, the common bearing retainer also has a vertical web and flanges that extend from the upper and lower edges of the vertical web to hold the bearing.
[0005]
The outer sliding member is generally attached to be secured to the cabinet by screws or other means, and the inner sliding member is also attached to be secured to the drawer. Often, a mechanism is provided so that the inner sliding member can be removed from the outer sliding member so that the drawer is fully removed from the cabinet. This mechanism must also allow the drawer to be reinserted into the cabinet so that the inner sliding member needs to be reinserted into the outer sliding member. The step of re-inserting the inner sliding member into the outer sliding member is accomplished by holding the bearing holder close to the front end of the outer sliding member facing the opening of the cabinet and thereby held by the bearing holder. This is more easily achieved when the bearing acts as an insertion guide for the sliding member. Further, if the bearing holder is not held in such a position, the inner sliding member is not aligned with the outer sliding member during the re-insertion process, so that the inner sliding member and the bearing holder are not aligned. Will come to accidental contact. Since the inner sliding member has a significantly greater thickness than the bearing retainer, this contact will damage the bearing retainer. Therefore, it is necessary to hold the bearing holder in front of the outer sliding member when the inner sliding member is removed from the outer sliding member.
[0006]
A common way to attach the outer sliding member to the cabinet is to provide a screw hole in the vertical web of the outer sliding member and use this screw hole to attach the sliding body to the cabinet. In a similar manner, the inner sliding member is attached to the drawer. The method of attaching such a sliding member to a cabinet or drawer is not, however, problematic. Access to the screw holes is often difficult when the sliding body is not extended. Access to the screw hole of the outer sliding member is obstructed by the inner sliding member when the outer sliding member web is placed against the cabinet. Similarly, access of the inner sliding member to the screw hole is obstructed by the outer sliding member when the inner sliding member web is placed against the drawer. Although this difficulty is alleviated by extending the inner sliding member, the extended sliding body may be accidentally damaged or injured by the protruding state. Extending the inner drawer slide also requires a larger working space for mounting the drawer slide with extended inner slide members extending out of the cabinet or enclosure. Furthermore, the extended drawer slide acts as a lever arm. Due to the weight of the extended drawer slide, the drawer slide turns about the attachment point. This rotation causes the drawer slide to tilt when it is installed, thereby resulting in misaligned attachment of the drawer slide.
[0007]
While other attachment methods are possible, these other methods also have problems. For example, the flange is formed integrally with the outer sliding member, and the flange has a screw hole for attaching the flange to the cabinet. In addition, a mounting bracket is welded to the outer sliding member, which also has a threaded hole for mounting the mounting bracket to the cabinet. However, the use of integrally formed flanges or mounting brackets requires the use of extra materials and extra manufacturing steps, thereby increasing the cost of the drawer slide. In addition, the flange and mounting bracket increase the size or stroke of the drawer slide and are undesirable.
[0008]
Furthermore, the attachment of the drawer slide to the cabinet and drawer is often done separately and the outer and inner slide members are only joined after being attached to the cabinet and the drawer, respectively. Therefore, as also mentioned above, the outer and inner members of the drawer slide must also be separable. This separation of the drawer slides allows access to the screw holes of the outer slide member and the screw holes of the inner slide member and eliminates the problems associated with extended drawer slide members.
[0009]
However, there is a bearing holder for holding a ball bearing that slidably connects the sliding members even if the drawer sliding body is separated. This bearing retainer also prevents access of the outer sliding member to the threaded hole of the vertical web. Forming openings in the vertical web of the bearing retainer is one way to allow access to the screw holes. The access hole is enlarged because the vertical web of the bearing holder only serves to hold the bearing in the correct relative position instead of the load bearing portion of the drawer slide.
[0010]
However, even if the access hole is enlarged, the bearing holder must still be correctly positioned with respect to the sliding member so that the screw hole can be accessed. Furthermore, the bearing holder may cause misalignment between the bearing holder access hole and the screw hole due to the movement of the bearing holder, even if the opening of the bearing holder and the sliding member are initially aligned. Must be restrained from moving. However, a small amount of play in this constrained bearing retainer is also required.
[0011]
SUMMARY OF THE INVENTION The present invention provides a drawer slide having an inner slide member and an outer slide member. The inner and outer sliding members each have a vertical web and upper and lower arms that form upper and lower tracks extending generally horizontally from the upper and lower edges of the web. . A plurality of bearings are adapted to roll into engagement with the web, the bearings being disposed in the bearing retainer and the opening and flange extending from the vertical web of the bearing retainer. A guide block is attached to the vertical web of the outer member, and the guide block includes a recess for receiving the bearing retainer protrusion with a loose mating engagement.
[0012]
Many of the attendant features of the present invention will be more readily understood by referring to the following detailed description and considered in conjunction with the accompanying drawings, in which like reference numerals designate like parts throughout, and in which: It will be.
[0013]
Detailed Description FIG. 1 shows a side view of a telescopic drawer slide. The drawer slide body of FIG. 1 is a three-element nested drawer slide body having an outer slide member 11, an intermediate slide member 21, and an inner slide member 31. The outer, intermediate and inner sliding members are slidably connected by bearings 19 and 29, the intermediate sliding member is stacked inside the outer sliding member, and the inner sliding member is stacked inside the intermediate sliding member. It has been. These sliding members can be extended in the longitudinal direction. Each sliding member has a longitudinal length (not shown in FIG. 1) that greatly exceeds the vertical height. As used herein, the longitudinal, vertical and horizontal directions are generally perpendicular and are used to describe the relative position of the structure of the present invention.
[0014]
The outer sliding member has a vertical web 13. Horizontal arms 15a, 15b extend from the upper and lower edges of the vertical web 13 in the same direction. Lips 17a and 17b extend vertically inward from the horizontal arms 15a and 15b. The horizontal arm, lip and vertical web therefore create upper and lower U-groove bearing raceways. The U-groove bearing race surrounds the upper and lower bearings 19 and is engaged with the bearings 19 for rolling.
[0015]
The outer bearing 19 is also in rolling engagement with the bearing track of the intermediate sliding member. The outer bearing 19 is thus slidably connected to the outer and intermediate sliding members. The intermediate sliding member has a vertical web 23 and horizontal arms extending from the upper and lower edges of the vertical web 23. The horizontal arm has a bent portion on the inner side in the vertical direction near the vertical web 23 forming the outer bearing tracks 25a, 25b facing the upper and lower sides of the intermediate sliding member 21 in the vertical direction. The outer bearing 19 is in rolling engagement with the outer bearing raceways 25a and 25b. The concave concave portion on the inner side in the vertical direction of the horizontal arm is followed by the concave concave portion on the outer side in the vertical direction forming the inner bearing tracks 27a and 27b facing the upper and lower vertical inner sides. The inner bearing 29 is in rolling engagement with the inner bearing tracks 27a and 27b of the intermediate sliding member. The inner bearings are held relative to each other by a bearing holder 41.
[0016]
The inner sliding member has a vertical web 33 and horizontal arms 34 a and 34 b extending from the top and bottom of the vertical web 33. The horizontal arm has a bent portion facing inward in the vertical direction to form a concave bearing raceway 35a, 35b on the outer side in the vertical direction. The inner bearing 29 is rollingly engaged with the tracks 35 a and 35 b on the outer side in the vertical direction of the inner sliding member 31.
[0017]
The bearing holder 41 has a cross section substantially similar to the cross section of the intermediate sliding member 21. The bearing holder 41 includes a connecting member 47 that forms a vertical web, and upper and lower outer flanges 43 a and 43 b that extend horizontally from the upper and lower edges of the connecting member 47. The upper and lower outer flanges 43 a and 43 b of the connecting member 47 include openings (shown in FIG. 2) surrounding the inner bearing 29.
[0018]
FIG. 2 shows a drawer slide with outer, intermediate and inner slide members. In the drawer sliding body, the intermediate sliding member extends from the inner sliding member and the outer sliding member, and the bearing holder extends from the inner sliding member and is located between the inner sliding member and the intermediate sliding member. And is shown. Such a state having a relative position between the sliding body and the bearing holder does not normally occur during operation of the drawer sliding body, but is shown in FIG. 2 to help understanding of the present invention. The outer sliding member is slidably connected to the intermediate sliding member 21 as described above with reference to FIG. The intermediate sliding member is slidably connected to the inner sliding member as described above.
[0019]
A guide block 68 is attached to the intermediate sliding member 21. The guide block 68 has a cross-sectional shape similar to that of the intermediate sliding member 21. The guide block has a vertical web and upper and lower stoppers 91a and 91b extending horizontally from the upper and lower edges of the vertical web.
[0020]
The bearing holder 41 is slidably connected to the intermediate sliding member 21 as described above. The bearing holder has a connecting member 47 that forms a vertical web. A planar extending member 61 extends from a part of the connecting member 47 along the bearing holder 41. A protrusion 63 is on the extension member 61. A recess 67 in the guide block 68 is adapted to receive the protrusion 63. The protrusion 63 of the extension member 61 and the recess 67 of the guide block 68 have the same shape to some extent.
[0021]
When the inner sliding member is removed from the drawer slide, the inner sliding member pulls or carries the bearing holder forward beyond the guide block. As the bearing retainer 41 moves past the guide block, the extension member, and thus its protrusion, moves beyond the recess 67. Eventually, the protrusion is carried and falls into the recess. Further movement of the bearing holder is prevented by contact between the bearing holder and the stopper or by contact between the protrusion and the rear wall 93 of the recess (shown in FIG. 4).
[0022]
FIG. 3 shows the protrusion of the bearing holder. As already described, the bearing retainer has a connecting member and upper and lower outer flanges extending from the top and bottom of the connecting member. The extension member 61 extends from the connecting member 47. The rear portion 60 of the extension member is proximate to the connecting member. The front edge 62 of the extension member 61 is the end from the connecting member.
[0023]
As shown in FIG. 3, the protrusion protrudes from the extending member toward the outer sliding member. The protrusion has an elliptical shape having a width larger than the length in the longitudinal direction. The protrusion has rounded edges 71a, 71b. The rounded edges 71a, 71b facilitate the movement of the protrusion 63 through the slight frictional contact surface caused by the contact between the protrusion and the guide block. Conversely, as the bearing retainer is moved away from the guide block 68, the round projection edges 71a, 71b facilitate escape from the projection recess 67. Further, although not shown, the extension member 61 can be removed such that the projection protrudes from the coupling member 47 of the bearing holder.
[0024]
FIG. 4 shows a guide block 68. As already described, the guide block has a vertical web and upper and lower stoppers 91a, 91b extending horizontally from the upper and lower edges of the vertical web. The upper and lower stoppers 91a, 91b are bent in the vertical outer direction, and the inner bearing races 27a, 27b facing the upper and lower vertical inner sides of the intermediate sliding member (as shown in FIG. 2), respectively. Try to satisfy. The stoppers 91a, 91b contact the upper and lower outer flanges 43a, 43b of the bearing holder and a part of the vertical web so that the bearing holder 41 is moved when the bearing holder is moved toward the guide block 68. Try to stop the exercise.
[0025]
The upper and lower stoppers 91a and 91b include an upper vertical bent portion 92b on the upper side and a lower vertical bent portion 92b on the lower side. When the curved portion on the inner side in the vertical direction is inserted into the outer or intermediate sliding member by contacting the inner sliding member with the tracks (35a, 35b) of the inner (considered two-member sliding body) sliding member To guide. Further, a guide rail 94 extends from the guide block 68 in the horizontal direction. As the inner sliding member 31 is inserted, the guide rail contacts one of the horizontal arms of the inner sliding member, thereby limiting the lateral movement of the inner sliding member. Thus, the stoppers 91a, 91b, in conjunction with the guide rails, help guide the insertion of the inner sliding member into the rest of the drawer slide.
[0026]
The vertical web of guide block 68 includes a lower surface 96 and an upper surface 98 that are adapted to be positioned proximate to the outer sliding member. When the guide block is attached to the outer sliding member (two-member sliding body) or the intermediate sliding member (three-member sliding body), the upper surface is insufficient to contact the connecting member 47 of the bearing holder. At a distance from the outer (or intermediate) sliding member. The guide block also includes a leading edge 90. The upper surface of the leading edge 90 can be chamfered. There is a recess 67 inside the upper surface. The recess 67 is defined by a front edge 97 extending vertically along the guide block and penetrating through the guide block. The recess 67 ends with a rear surface 93. The rear surface 93 extends vertically along the guide block. The side edge surfaces 100a, 100b form the sides of the recess 67 and connect the front edge 97 to the rear surface 93. The volume defined by the side edge surfaces 100 a, 100 b, the front edge 97 and the rear surface 93 forms a recess 67.
[0027]
During normal operation of the drawer slide, the protrusion is not located inside the recess. Instead, the longitudinal movement to a position where the bearing holder is close to the guide block but not abutting the guide block is limited. However, this condition changes when the inner sliding member is removed from the other sliding member. This removal and its effects are described below for a two-member sliding body.
[0028]
The inner sliding member is removed from the outer sliding member by extending the inner sliding member past the outer sliding member. The extension of the inner sliding member through the outer sliding member generally requires the use of some kind of latching mechanism, which is well known in the art. When the inner sliding member is extended through the outer sliding member, the inner sliding member further exceeds the normal running length of the bearing holder through the frictional force that causes the rolling engagement of the ball bearing. And pull in the longitudinal direction. This extra travel results in a protrusion in the bearing retainer located in the recess.
[0029]
The rear surface 93 of the guide block limits the movement of the bearing retainer toward the guide block by contact with the front edge 62 of the extension member 61. As already described, the contact between the round projection edges 71 a, 71 b and the front edge 97 of the recess 67 eliminates the movement of the bearing holder 41 away from the guide block 68. A small amount of translational force applied to the bearing holder 41 away from the guide block 68 releases the loose engagement between the protrusion 63 and the recess 67. This small amount of translational force is applied when the inner sliding member is reinserted into the outer sliding member.
[0030]
FIG. 5 shows a drawer slide body in which the bearing holder 41 is arranged such that there is a protrusion in the recess of the guide block. The leading edge 62 is in contact with the rear surface 93 of the guide block. The protrusions in the recesses align the vertical web openings of the bearing holder so that the screw holes in the outer sliding member 11 are exposed.
[0031]
In the engagement position shown in FIG. 5, the protrusion is not in contact with the edge of the recess because the recess is larger in size than the protrusion. Accordingly, the bearing holder can move to some extent because the recess has a larger dimension than the protrusion. As a result, the protrusions are loosely engaged and allow some movement of the bearing retainer, but the bearing retainers are greatly limited by the protrusion extending into the recess.
[0032]
FIG. 6 shows a bottom view of the protrusion engaged in the recess. The side surfaces of the recesses 100a and 100b are separated from each other by a distance larger than the distance between the side surfaces of the protrusions 73a and 73b. The protrusions are substantially concentric with the recesses, and the size of the protrusions is equidistant from the side surfaces of the recesses 100a, 100b. Thus, the protrusions float in the recesses, and the protrusions provide some room for longitudinal movement and, if necessary, room for lateral movement.
[0033]
FIG. 7 shows a cut-away side view of the protrusion engaged in the recess. The protrusion is centered in the recess, and the side surfaces of the protrusions 73a and 73b are equidistant from the side surfaces of the recesses 100a and 100b. Furthermore, the bottom of the connecting member 47 that is the side surface of the connecting member close to the guide block is not in contact with the top of the guide block. This allows the bearing retainer to float and the protrusions allow the guide block to be in the recess without biasing or contacting or engaging the connecting member. As shown in FIG. 7, the protrusion is formed by making a recess or by embossing the connecting member. Alternatively, the protrusions are formed by forming the connecting member from a single piece of thick material and machining a portion of the connecting member to form the protrusion, or by depositing or depositing material on the connecting member. Thus, it can be formed.
[0034]
FIG. 8 shows another embodiment of the present invention. In this embodiment of FIG. 8, the drawer slide is shown with its various components in the same relative position to each other as the drawer slide shown in FIG. However, in the drawer slide shown in FIG. 8, the bearing holder 41 and the guide block 68 are changed so that two small dents and two recesses are arranged in the bearing holder and the guide block, respectively. One of the small recess and the recess can be used instead. More specifically, the web of the bearing holder has a cross-sectional shape similar to that of a cap, and the top portion of the web 47a is connected by an inclined portion to two running portions 64a and 64b that form opposite edges of the web. . The upper and lower outer flanges of the bearing holder extend at right angles from the web at the opposite edges of the running portions 64a, 64b. The bearing holder of the sliding body in FIG. 8 does not include a connecting member, and instead, small recesses 62a and 62b are directly arranged in the running portion of the bearing holder.
[0035]
Each traveling part of the guide block includes recesses 60a and 60b. These recesses are slightly larger than the size of the small recesses in the bearing retainer and are adapted to accept these small recesses with a loose mating engagement.
[0036]
FIG. 9 shows the bearing holder of the embodiment of FIG. The bearing holder shown in FIG. 9 has top portions 47a where the downwardly inclined portions 111a and 111b are connected to the running portions 64a and 64b of the bearing holder. Upper and lower outer flanges extend substantially perpendicularly from the run. Small dents 72a and 72b are placed inside the region defined by the running portion, approaching the longitudinal end of the bearing holder.
[0037]
FIG. 10 shows a guide block used with the other side of FIG. The guide block of FIG. 10 differs from the guide block of FIG. 4 in that a recess is disposed in each of the travel portions 98a and 98b of the guide block instead of the central portion of the guide block. Otherwise, the guide block of FIG. 10 is the same as the guide block of FIG. Furthermore, the material can be removed from the central part of the guide block to save material or to further ensure that the bearing retainer does not accidentally contact the guide block.
[0038]
FIG. 11 shows a bottom view of a guide block in which a small recess is placed inside the recess. The size of the recess is substantially larger than the size of the small recess. Thus, the edge of the small recess does not contact the edge of the recess. This provides a loose mating engagement that allows some movement of the bearing retainer when the small recess is in the recess. Further, as shown in FIG. 12, a gap exists between the bearing holder and the guide block, so that most of the top portion of the bearing holder 41, the downward inclined portions of the bearing holders 111a and 111b, and the bearing holder. The traveling portions 64a and 64b of the tool 41 are prevented from contacting the top portion of the guide block and the downward inclined portion of the guide block or the traveling portion of the guide block. Therefore, the bearing holder is not biased when a small recess is held in the recess.
[0039]
Therefore, this invention provides the drawer | drawing-out sliding body which has a bearing holder restraint part. Although the present invention has been described in certain specific embodiments, many additional modifications and variations will become apparent to those skilled in the art. Therefore, it will be understood that the invention may be practiced otherwise than as specifically described.
